Collective modes in non-Hermitian fermionic superfluids
Gabriel Angelo V. Vila, Kristian Hauser Villegas
The Higgs and Nambu-Goldstone modes are paradigmatic collective excitations in superconductors and superfluids. These modes are commonly analyzed within the pseudospin formulation…
Simulating Majorana fermions in black hole with Ising Models
John Vienn A. Estremadura, Kristian Hauser A. Villegas
Quantum field theory (QFT) in curved spacetime has led to profound predictions, including the Unruh effect and Hawking radiation, yet their direct observation remains extraordinari…
Bosonization in -paraparticle Luttinger models
Dennis F. Salinel, Kristian Hauser A. Villegas
Alternative theories of quantum statistics provide an avenue for exploring novel physics beyond bosons and fermions, yet experimental verification of their existence in nature prov…
Holographic superfluid sound modes with bulk acoustic black hole
Joseph Carlo U. Candare, Kristian Hauser A. Villegas
The sound modes of a flowing superfluid is described by the massless Klein-Gordon equation in an effective background metric. This effective background metric can be designed to mi…
Quantum geometric tensor in systems with fractional band dispersion
Jamme Omar A. Biscocho, Kristian Hauser A. Villegas
We investigate the quantum geometric tensor, which is comprised of the Berry curvature and quantum metric, in a generalized Dirac two-band system with non-integer dispersion $E(\ma…
Theory of pseudospin resonance for multiband superconductors
Kristian Hauser Villegas
We formulate a generalized pseudospin formalism for multiband superconductors in the presence of an external perturbing electromagnetic field. Our theory naturally captures the eff…
Theory of BCS-like bogolon-mediated superconductivity in transition metal dichalcogenides
Meng Sun, A. Parafilo, K. H. A. Villegas +2
We report on a novel mechanism of BCS-like superconductivity, mediated by a pair of Bogoliubov quasiparticles (bogolons). It takes place in hybrid systems consisting of a two-dimen…
Unconventional Bloch-Grüneisen scattering in hybrid Bose-Fermi systems
Kristian Hauser A. Villegas, Meng Sun, Vadim M. Kovalev +1
We report on the novel mechanism of electron scattering in hybrid Bose-Fermi systems consisting of a two-dimensional electron gas in the vicinity of an exciton condensate: We show…
